Neem oil
By Patty on 06/20/2012
Very fast delivery of product. I have applied it, but don't know yet whether it will be effective. I have used it on azaleas but the leaves continue to turn yellow. However they do have healthy looking new growth so maybe there is hope. I also used it on a mature gardenia that has always had a white fly problem and it does look better than it ever has before.

The jury is still out at this point in time

Purchased Neem oil because the marketing materials describe what Neem can be use for to protect against specifically black spot. Have used 3 bottles in 3 weeks now on our apple trees & I can detect slight improvement. Will continue to use Neem thru the whole box right up until harvest then will reevaluate as to its effectiveness.
